There is definitely some stupid shit in this MC's brain.
But enough yuck; I will say that I absolutely love the Japanese mercantile traditions' mannerisms.
"Thank you for your continuing support" is a totes normal phrase, but the implications of allowing the others to support you, with an understanding that doesn't imply expectations?
It's hella subtle, totally polite, and gives the other party all the choice; exactly how a merchant should behave.
Iunno, it was just kinda neat; maybe it's just my edible.... 😅😅 ¯\(ツ)/¯
